Both the external coil and capacitor determine the
frequency response of EQ output.
The series connected resistor is for damping.

In the intercarrier system, the following phenomenon should be considered;
a strong equalization (EQ) enlarge the sound carrier output from pin 22, because the EQ is applied before an audio trap.
In that case, the next two solutions are recommended;
decrease in S level of SAW, avoiding to peak a sound carrier in EQ.
